Birkenstock Bonn 39

Retired style, birkenstock bonn. Similar to the Boston but with a back strap. In almost brand new condition. There are some scuffs and barely noticeable marks. One strap has separated from the side but it doesn’t compromise wearability or function and can be easily fixed ( will leave this up to the buyer). Size 39 narrow. Fits my size 8.5 foot great.
